Referidas aberturas 20, 22, 30, 32 são conectadas a respectivas tubulações 200, 300, pelas quais fluem os fluxos hidráulicos “A” e “B”, respectivamente. [016] The first device 20-21 -22 is formed: by first hydraulic flow inlet opening 20; by the first semi-cylindrical region 21 of the casing, in which the inlet opening 20 opens and through which the rotor blades 3 pass; by first hydraulic flow outlet opening 22, derived from said first semi-cylindrical region 21 and opposite and aligned to said first inlet opening 20; and by first hydraulic flow “A”, which is received at the first inlet opening 20, fed into the first semi-cylindrical region 21, where it pushes the blades 3 and these rotate the axis 2, first hydraulic flow “A” which leaves through the first opening exit 22.

A tomada de saída de força 6 pode ser acoplada a um equipamento qualquer, preferencialmente a um gerador 100 que produz energia hidroelétrica usada para uma finalidade qualquer. [018] Thus, in operation (fig. 1), the first hydraulic flow “A” enters through the first input opening 20, which feeds it into the first semi-cylindrical region 21 of the housing, where said first hydraulic flow “A” collaborates to push and rotate the blades 3 and the shaft 2 through a trajectory “C” corresponding to the first half of the rotation cycle of the rotor 2-3; the second hydraulic flow “B”, opposite the first hydraulic flow “A”, enters through the second inlet opening 30, opposite the first inlet opening 20, and said second hydraulic flow “B” is fed into the second semi-cylindrical region 31 of the housing , opposite to the first semi-cylindrical region 21 , in which, referred to second hydraulic flow “B” collaborates to push and rotate the blades 3 and the shaft 2 along a trajectory “D”, corresponding to the second half of the rotation cycle of the rotor 2-3, thus completing one rotation cycle of the latter; said first “A” and second “B” hydraulic flows leave the respective opposite semi-cylindrical regions 21 and 31 of the housing through the first 22 and the second 32 outlet openings, respectively. In this way, when the blades 3 of the rotor 2-3 pass through the first semi-cylindrical region 21 of the housing they receive impulse through the first hydraulic flow “A” and when they pass through the second opposite semi-cylindrical region 31 they receive a second impulse through the second hydraulic flow “B ” thus providing continuous thrust to the blades 3 and greater efficiency in converting the kinetic energy of the hydraulic flows “A” and “B” into mechanical energy in the shaft 2 and in the extended power output take-off 6 thereof, thus optimizing the performance of the hydraulic turbine of cross flows 1 . The power output socket 6 can be coupled to any equipment, preferably to a generator 100 that produces hydroelectric energy used for any purpose.
